APPARATUS FOR AUTOMATICALLY MIXING FIRE-EXTINGUISHING SUBSTANCES WITH WATER.

SPECIFICATION forming part of Letters Patent No. 528,441, dated October 30, 1894.

Application filed Ju y 2,1894. $erial No. 516,399- (No model.) Patented in Germany May 1,1891, No- 60,346; in Austria-Hungary October 31,1892, No.19,144 and No. 51,591, and in Era-nee June 13} 1893,1To. 230,8Z7i

To all whom it may concern.-

Be it known that I, GEORG MiiLLER, a subject of the Emperor of Germany, and a resi-- dent of Kaufbeuren, Bavaria, Germany, have 5 invented certain new and useful Improvements in Apparatus for Automatically Mixing Fire-Extinguishing Substances with Wator, (for which I have obtained patents in Germany, No. 60,346, dated May 1, 1891; in Austria-Hungary, No.19,144 and No.'5l,591, dated October 31, 1892, and in France, No. 230,827, dated June 13, 1893,) of which thefollowing is a specification, reference being made to the annexed drawing, showing in elevation, partly in section, the said apparatus.

This apparatus consists of a chamber having a removable cover adapted to be fixed and communicating at its lower end with a pipe e which extends across beneath the chamber and terminates at a and b where hose are adapted to be connected so that this pipe e may form apart of the conduit between the source of water and its delivery, for instance between the hydrant and the delivery nozzle.

Communication between the chamber 0 and pipe e may be closed by a valve g or the latter may be set by hand wheel h to regulate the amount of said communication.

The vessel 0 may be cylindrical, and within it there is placed a second cylindrical vessel (1 of smaller diameter having perforated walls and a perforated bottom f.

The vessel 01 rests with its lower edge on, the flange c at the base of chamber 0 and its wall separates the valve g from the annular space surrounding the vessel d within the chamber a, At its upper end the vessel 01 is centered within the conical flange c. The 0 said annular space surrounding the vessel 11 communicates direct with the pipe 6, preferably toward the inlet end of said pipe, by a branch pipe c' in which is a cock la. The whole rests on legs h The vesseld is removable, and is intended 5 to be filled with any suitable materials which when dissolved or suspended in water will assist in the extinguishing of fires, and to be placed in the chamber 0 which is then closed.

When required for use, the apparatus is carried to a suitable position and the hose or the like attached by which the water to be poured on the flames passes through the pipe 6. The valve 9 is thenopened and also the cock is and some of the water passes through the pipe 2' into the vessel (1 and dissolves or takes up the material therein and issues past the valve g. The water passing direct along pipe e helps to suck the water through pipe '5 and vessel (1 and mingles therewith. The action of the apparatus may be controlled by manipulation of cook 70 and valve g.

I claim as my invention An apparatus comprising a chamber 0, a flange c at the base thereof, a flange c, a

removable vessel cl adapted to rest on said flange 0 having perforated walls anda perforated floor f, a valve 9 at the base of chamber c, a pipe e having open ends a b and communicating with said chamber 0 by way of valve g, a branch pipe i from pipe 6 to chamber 0 below flange c, and a cock in in said pipe 2', the whole substantially as and for the purpose set forth. 7

In witness whereof I have signed this speci- 7 5 fication in presence of two witnesses.
